Detailed explanation-1: -Mules and bananas are examples of hybrids that are infertile, so they cannot have their own babies.

Detailed explanation-2: -By far the most well-known species concept is the biological species concept, which was proposed by evolutionary biologist Ernst Mayr. The biological species concept states that a species is a group of actually or potentially interbreeding natural populations which are reproductively isolated from other such groups.

Detailed explanation-3: -A species is the most specific of the common taxonomic ranks. The members of a species are all closely genetically related. Another feature of a species is that the organisms within a species can mate and produce fertile offspring. A lion and a tiger are not the same species even though they belong to the same genus.
